Use //IGNORE to ignore words that cannot be converted

phpiconv("UTF-8", "GBK//IGNORE", $text);

Upstairs says the designation ignore is a bit, but this article still has the problem of the bug, simply wrote down:

There is almost no introduction to this bug in the Chinese website, the English site is mentioned, but it is not clear, and now do not know which or which version of the bug, in short, the installation of the environment when the latest iconv will not have a problem.
